Whenever you can pick up a higher grade Amazing Spider-Man within the first 10, I think it's a great investment. Even if it's not a huge bargain now, it will be. Over time key Amazing Spider-man's always go up.

Sounds like you have some great books. I just looked at your collection overview, 9000 issues from Marvel alone! wow! You should put some of those great issues in your display case so that we can see them. (I need to put books in my display case too) You can put 24 issues in the display case now.
